vented an Improvement in Yarn Spinning or Twisting Apparatus, of which the following description, in connection with the accomures on the drawings representing like parts.

This invention relates to yarn spinning or twisting apparatus, and more particularly to forms of such apparatus wherein high spindle speedis attained-such, for instance, as from Lien to fifteen thousandretelutions perminute-it being manifest that, other things beingequal, increased production per frame is the result of increased spindle speed.

In a recent type of spinning or twisting apparatus the annular traveler support or ring is arranged to rotate freely when the spindle is in motion, and when so rotating the ring is free to yield in any direction under unbalanced strains, the rotation of the ring obviating the destructive heating of the traveler by friction against the ring. The traveler used in such apparatus has, as usual, two bearingpoints on the rotatable ring; but in practice certain objectionable features have developed, one of which is the difficulty of at times controlling the momentum of the'ring, due to the very rapid rotation of the ring; such difficulty being particularly noticeable when stopping the frame. It has also been found necessary to provide elaborate means forcushioning or' yieldingly controlling thelateral or radial movements of the ring.

Our present invention has among other objects the production of means for obviating the objectionable features hereinabove referred to; and in the practical embodiment of our invention we utilize the usual principle of a traveler with two bearing-points;-

but we have provided fixed and movable races or supporting-surfaces for the bearingportions of the traveler, whereby the friction of the latter is governed by engagement with the fixed race or surface, while still permitting Serial 1%, apas. on; model.)

the traveler to carry 'or rotatively move the other race or supporting-surface with it.

It is well known t5 those skilled in spinning or twisting apparatus that atravelerby or through centrifugal action bears harder on the inner flange of thering, and in the preferred form of our present invention the inuer supporting surface or race is permitted to rotate with the traveler, thus diminishing the frictional resistance, while the outer engage ing portion of the traveler bears on or travels upon the outer fixed race.

We have herein shown our no-vel duplex.

travelensupport, as it may be termed, so constructed that it will lit the usual ringholder, so that old or common rings of wellknown construction may be replaced by our.

improved traveler-support without necessitating furtherchange ofthe parts.

Referring'now to the drawings,'which illustrate a practical embodiment of our invention, Figure l, in elevation and partlyiu section, represents the spindle-rail, spindle and bobbin, ring-rail, and one form of our novel traveler-support or ring on the line a; m, Fig. 2, the spindle and bobbin beingbroken offt'o save space.

parts shown in Fig. 1, the spindle and bobbin being omitted. Fig. 3 is an'enlargedsectiou detail on the line a: m, Fig. 1. Fig.4 is a part, elevation and section of a modified form of our invention on the line yy, Fig. 5; and Fig. 5 is a top or plan view of the traveler-support and traveler shown in Fig. 4.

Fig. 2 is a top or plan view of the Our invent-ion is not restricted to use in connection with any particular type of spinning o'r twisting frame, and herein the spindle-rail 2, reciprocating ring-rail 3, spindle4 of any suitable high-speed type, provided with a whirl 5 for the driving band or belt 6,, ac-

extend, may be and are all of well-known or usual construction in spinning or twisting apparatus, it being understood that each ringrail has a plurality of the apertures 8 correspending to the number or spindles. We havealso shown swell-known form of ringhoider, comprisingn sheet-m etel annular base 12, radially notchedat its periphery at 13 to receive the shanks of beaded screws 14-, which secure the holder to the ring-mil, struck-up or bent lugs or cars 15 on the base serving to hold the treveler-snppbrt or ring in place, it being understood that the inner circumferentiel portion 16 of the base extends inward somewhat beyond said relaining lugs.

- Referring: now more particularly to Figs. 1, 2, and 3, our novel traveler-support is shown as comprising inner and outer concentric and relatively-movable members or rings 20. 30, separated by a suiiicient space or clean.

ence 19, Fig. 3, to permit free but limited re.-

dial movement of the inner member 20, which letter is provided at its upper end with an intnrned circular flange 21, which constitutes a traveler-race or so pportingsn niece, the foot of the said member. beingshown as thickened or enlarged in cross-section to provide additional weight ldr steedying itsmovem'ent,

end herein the foot is shown as provided with an externalnnnuler projection or'rib 22. The

part 16 of the holder 12 projects beneath the foot of the inner member 20 and supper-Lethe same when at rest; The outer member has at its upper end an ontwnrdly extended circular flange 31, which retains. the traveler in place and at times forms a race therefor, the main rece, however, being-termed by the upright outer fecedil of the member 30, the

. widened foot 34 of said member (sceyFigsfl and 3) being engaged-and held stationery by frictional contact-with the lugs 15'of. the

holder, while the inner side of the foot-has an annular overhanging shoulder 32, beneath which the rib or projection 22 oftherotatable member 20. free'lyeirtends, the'clearance between the rib-shoulder permitting axial or up-and-down movement of the member-20.

The traveler 40, of well-known form lise its ends 41 42 extended inwardlmend ,it is.

adapted to travel on the races formed on the fixed and movable members of the duplex ring or traveler-support described;

The yarn passes from the usual deliveryrolls and 'pigteil or-gnide (not shown) through the traveler to the bobbin, and when the spindle and bobbin are rotated at high speed the pull of the yarn causes the traveler to re-. volve about the double race, at such time the traveler, by its friction on the rotatable ring, causing it to rotate with inereasingrapidity until to all appearances the traveler and ring move in unison. At the same time the. tension of the yarn raises the rotating ring from engagement with the foot or projecting part 16 of the holder, undue lift of the ring being prevented by the shoulder 32 of thefixed ring or member 30; and at the some time the travslot is moved by centrifugslforce into substsntiailly the position shownin Figs. 1 and 3, its end 42 traveling upon the upright beering-snrface 33 of the fixed ringl When the .tween the fixed and rotatable members of the rotatable member is rotating at full speed} "it rarely contacts with the fixed member, seeining to center itself and adjust itself axially in the so-called rotary ring-spin ins appurntus, herelnbefore referred to. So' fares we are able to discover the clearance between the fixed and movable members forms practically an air-cushion which is self-adapting. 75

to the requirements of the apparatus. The v engagement of the traveler with the fixed and movable members appears also to aid in main; taining the parts inproper eoncen tric position when in operation, The clearance be-- traveler-support or ring also; permits suffic'icnt movement of the rotatable member to counteract the ode-ct of sudden strains.v

In the drawings the rotatable member is85 not shown as lifted by the tension of theyarn in order to more, clearly show the clearance between the shoulder-32 and rib 22. v

We prefer to make the innermember rotatable; but, if desired, the arrangement may 0 be reversed, as shown in Figs. Mind 5, wherein. the inner' membcr 50 hasatits foot an extel-nail flange 51, tobe engaged and held from v rotation by the lugs 15 of the'holder, an intnrned flange 52st the top of the member 5 50 formingthe. race for the traveler, while thoouter member 60, loosely surrounding the inner member, rests on the flange-51 when the apparatus is at rest. The outer rotatable member has at its upperend an outwardlywe extended flange 61 to retain the traveler in place when starting up, and as full speed is attained the ofuterend of the traveler will en gage the upright face or race 62 below the flange, the member 60 then being lifted from 10 its so pport and r'otst-ing freely about the fixed member 50.-

Fig. 4 the inner member 50 is sprung into the z 15 holder and the outer member 60 dropped into place surrounding the fixed member.-

. It will be manifest that our duplex ring of either form herein shown can be readily sub-- stituted in a frame for rings now in use, u ti l-'- 12o izing the old holders.

Our invention is not restricted to the precise' construction and arrangement herein shown, asythesame may be varied or. rearranged without departing from the spirit and r 2 5 scope of our invention;
